Introduction: Increasing resistance to antimicrobial agents is typically one of the main problems of health care. Control the dispersion of bacteria in different environments is a challenge in this section that to the overcome of them is essential for health and economic. In this study, nano-silver antibacterial activity was studied against Gram-positive bacteria Staphylococcus aureus and Pseud...
The pharmacologic field that studies antimicrobial pharmacokinetics and pharmacodynamics (PK/PD) has had a major impact on the choice and dosing regimens used for many antibiotics especially those used in the treatment of respiratory tract infections. PK/PD parameters are particularly important in light of increasing antimicrobial resistance. Drug pharmacokinetic features, such as serum concent...
OBJECTIVES Bacterial resistant infections have become a global health challenge and threaten the society's health. Thus, an urgent need exists to find ways to combat resistant pathogens. One promising approach to overcoming bacterial resistance is the use of herbal products. Green tea catechins, the major green tea polyphenols, show antimicrobial activity against resistant pathogens. The presen...
The objective of this work is to investigate the antibacterial activity of Artocarpus heterophyllus plant. The antibacterial activity of essential oil obtained from plant was examined. To evaluate the antibacterial activities of these extracts; their in vitro antibacterial activities were determined by disk diffusion testing and minimum inhibitory concentration (MIC). Escherichia coli, Pseudomo...
Background and Objectives: Melissa officinalis belongs to plant Lamiaceae family and is native to Iran as well as other countries. The aim of this study was to identify chemical compositions and antioxidant activity of the M. officinalis essential oil (EO). Another aim of this paper was to assess antimicrobial activity of M. officinalis EO on growth of clinical and commercial strains causing in...
The antibacterial activity and mechanism of berberine against Streptococcus agalactiae were investigated in this study by analyzing the growth, morphology and protein of the S. agalactiae cells treated with berberine. The antibacterial susceptibility test result indicated minimum inhibition concentration (MIC) of berberine against Streptococcus agalactiae was 78 μg/mL and the time-kill curves s...
The microbicide candidate octylglycerol inactivates sexually transmitted bacterial pathogens at concentrations which spare normal vaginal flora (lactobacillus). Standard minimum microbicidal concentration assays and time-kill assays revealed the drug concentrations and times required for inactivation. Octylglycerol concentrations must exceed the binding capacity of any human serum albumin to be...
INTRODUCTION The aims of this study were i) to define the chemical constituents of Cuminum cyminum (cumin) essential oil, ii) to compare the antimicrobial activity of this oil to that of chlorhexidine (CHX) and co-trimoxazole on planktonic and biofilm forms of bacteria isolated from the teeth with persistent endodontic infection and iii ) to compare the cytotoxicity of these medicaments on L929...
This study was conducted to isolate and observe the morphological biochemical characteristics of bacterial strains present in sandwich. A single colony isolated from a sandwich collected different restaurants located area University Rajshahi by plating diluted primary suspension liquid medium onto an agar solidified mineral salt after purifying through filter paper. The bacterium found be Gram-...
